Once a fault is detected, the MCB automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.

Miniature circuit breakers protect wires and cables in cases of short circuit and overloads and are a fundamental component in end-to-end protection concepts.

The dual 5-channel Trusted® Power Distribution Unit Miniature Circuit Breaker (MCB) 24 V is designed for N+1 or 100 % redundant 24 Vdc power distribution applications. The unit is designed to be mounted on a standard DIN rail.
